WINSTON-SALEM, N.C. -- Investigators with the Winston-Salem Police Department are trying to figure out how three to four alleged robbers entered a senior living community and robbed the tenants of televisions, jewelry and other personal belongings.

"It's hard for a normal person to understand why someone would do something like that," said Lt. Rob Cozart.

C.D. Williams' wife has lived in the home for six months and he says it's a shame.

"My wife is OK. They went into the room right across from her. where she was. They broke the door jam," Williams said.

To get inside Clare Bridge, visitors either need a pass code or have someone inside with that code, open the door.

Cozart says it's not clear how the robbers got into the facility without breaking doors or windows.

"They didn't kick in the door, or break the window and crawl in, or something like that. They were able to access the facility," he said. "Makes you lose a little faith in humanity, especially, this time of year coming up on the holidays. It's hard to believe somebody could stoop that low,"

According to police, a suspect grabbed one of the residents during the attack but she was treated in the home and is doing fine.

"You don't know where to go now to be safe. It's crazy. People are doing crazy things. You don't think you're safe anywhere anymore," Williams added."It's somebody that's lower than a snake's belly, from what I can say. And that's pretty low, isn't it?"

Brookdale Senior Living, Clare Bridge's parent company, said it is making sure all their residents, family of residents and staff are aware of the incident.

"We are grateful for the immediate support from local authorities and are working closely with them on the investigation," a Brookdale spokesperson said in a statement. "We took immediate action to review security protocols and to ensure ongoing safety because the safety of our residents and associates is a top priority."
